FS-020CBER5000JE Equivalent & Substitute Parts

Part Overview

The FS-020CBER5000JE is a 500 mOhms ±5% 20W through-hole radial wirewound resistor manufactured by Vishay Huntington Electric Inc. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design and procurement requirements. The radial package configuration and wirewound composition provide stable performance across industrial temperature ranges. Substitute parts must maintain electrical equivalence in resistance value, power rating, and tolerance specifications while accommodating potential package geometry variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 500 mOhms (exact match)
• Power rating: 20W (minimum requirement)
• Composition: Wirewound (mandatory for thermal stability)
• Temperature coefficient: ±400ppm/°C (matching thermal behavior)

Tolerance Consideration: The original part specifies ±5% tolerance. Substitute parts with ±10% tolerance represent a relaxation of accuracy specifications and are acceptable only where circuit design permits wider tolerance margins.

Package Compatibility: Radial and axial package configurations are mechanically distinct. Radial packages use parallel leads; axial packages use leads at opposite ends. Selection depends on PCB layout requirements and available mounting space.

Regulatory Compliance: All substitute parts must maintain RoHS3 compliance and MSL Level 1 (unlimited moisture sensitivity) status to ensure regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: FS-20SCBER5000JE9 (Vishay)

This part is the manufacturer-recommended equivalent. It maintains identical electrical specifications (500 mOhms, ±5% tolerance, 20W, ±400ppm/°C) and regulatory compliance (ROHS3, MSL 1). The radial package configuration matches the original design. The only dimensional difference is increased length (2.375" vs. 2.000"), which requires verification of available PCB mounting space. Active product status ensures long-term availability and supply chain stability.

Secondary Substitute: B20KR50E (Ohmite)

This part meets all critical electrical requirements (500 mOhms, 20W, ±400ppm/°C, wirewound composition) and maintains RoHS compliance. The tolerance specification is ±10%, representing a relaxation from the original ±5%. The axial package configuration differs from the original radial design, requiring PCB layout modification. Identical physical dimensions (0.437" Dia x 2.000" L) to the original part facilitate potential mechanical compatibility. Active product status supports procurement viability.

Selection Criteria:

• For direct PCB replacement without layout modification: Select FS-20SCBER5000JE9. Verify that the increased length (2.375") accommodates available mounting clearance.
• For tolerance-critical applications: Select FS-20SCBER5000JE9 (±5% tolerance matches original specification).
• For applications permitting ±10% tolerance with axial package compatibility: B20KR50E is acceptable.

Frequently Asked Questions (FAQ)

Q: Can FS-20SCBER5000JE9 directly replace FS-020CBER5000JE without circuit modification?

A: Electrical substitution is direct. The resistance, tolerance, power rating, temperature coefficient, and operating range are identical. Mechanical verification is required: the substitute is 0.375" longer (2.375" vs. 2.000"). Confirm that PCB mounting space and component clearance accommodate this dimension increase.

Q: What is the tolerance difference between the original and B20KR50E substitute?

A: The original FS-020CBER5000JE specifies ±5% tolerance; B20KR50E specifies ±10% tolerance. This represents a two-fold relaxation of accuracy. Substitution is valid only if circuit design calculations confirm that ±10% resistance variation remains within acceptable operating parameters.

Q: Why is the package type different for B20KR50E?

A: B20KR50E uses an axial package (leads at opposite ends) while the original uses a radial package (parallel leads). This difference requires PCB layout modification. Axial packages occupy different mounting footprints and may not fit existing radial component pads without redesign.

Q: Are all substitute parts RoHS compliant?

A: Yes. FS-20SCBER5000JE9 is ROHS3 compliant; B20KR50E is RoHS compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the inventory status for substitute parts?

A: FS-20SCBER5000JE9 has 1033 pieces in stock; B20KR50E has 904 pieces in stock. Both are classified as active products with established supply chains.

Q: Can B20KR50E be used in high-temperature applications?

A: The operating temperature range for B20KR50E is not specified in available data. The original part and FS-20SCBER5000JE9 both support -55°C ~ 350°C operation. For applications requiring confirmed high-temperature performance, FS-20SCBER5000JE9 is the recommended choice.
